Answer:
18 ft
Step-by-step explanation:
Ok, so if he walks 4 miles per 64 minutes, or 4 miles/64 min which will
reduce to 1 mile/ 16 min, then the numbers of miles he walks in a given
number of minutes would be
1/16 * number of minutes
The question states we represent miles with y and number of minutes with x, so...
y = 1/16x
So let's check it...
How many miles (y) in 64 minutes (x)
y = 1/16x
y = 1/16 * 64
y = 64/16 = 4 miles
Yep! It checks!
Answer:
Equation of line: y = ![\frac{2}{5}x](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7Dx)
Step-by-step explanation:
So we have to calculate the slope. The formula is ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
Slope =
=
=
= ![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
We then need to calculate the Y-intercept.
The formula is
y - 200 =
(x - 500)
y - 200 =
x - 200
Add 200 to both sides
y = ![\frac{2}{5}x](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7Dx)
There y-intercept is 0 which is the origin (0,0)
